Keep in mind, that Xampp is NOT a software, it is a collection (and/or distribution) of different software products. The goal of Xampp is NOT(!) developing Apache or MySQL or similar, but to provide an "easy to install" distribution.

In case of severe software bugs in Apache, you should contact the Apache development team, which of course is not present here. All this explains, why nobody can help you here - you are simply in the wrong forum.
